MACHINE FOR GUIDING BOBBINS IN RUNNING PATHS.

Application filed August 30,1921. Serial No. 497,078.

T 0 all whom it may concern Be it known that I, ALFRED QRTHMANN, residing at Barmen, Blankstr. 3, Germany, have invented certain new and useful 1mprovements in and Relating to Machines for Guiding Bobbins in Running Paths, of which the following is a specification.

This invention relates in general to braiding machines. The object of the invention is to provide a machine in which the entire means for guiding the bobbin carriers consists only of arcuate guiding surfaces. This is accomplished by arranging the sections of the raceway along which the bobbin carriers travel in diflerent planes or along the peripheries of concentric circles. The bobbin carriers themselves are preferably withguide members which in addition to guiding the carriers along the part of the raceway with which they cooperate, also enable them to pass from one section of raceway to another in a satisfactory manner. In guiding the bobbin carriers from one section of raceway to another the said guide members are assisted by cams that revolve with the bobbin drivers and bear against the guide members when the bobbin-carriers pass from one section of raceway to another. The said cams and guide members are also arcuate in shape.

The invention is illustrated by way of example in the drawing-in which- Fig. 1 is a vertical section through a fragment of a braiding machine with raceways formed in vertical circular plates,

. Fig. 2 a horizontal section on the line A-B of Fig. 1,

Fig. 3 a vertical section through a number of raceway sections or plates taken on the line 0-D of Fig. 1, and I Fig. tis a similar section on the line E--F of Fig. 1. I

In the drawing a is the lower part and b the upper part of a circular raceway. As shown in Fig. 1 these lower and upper parts lie in two different planes or, more correctly speaking in two different concentric circles, the part 7) being nearer to the center of the machine than the part a of the raceway. Attached to the bobbin carriers 0 are guide pieces or members d, e which cooperate or engage with the parts a and b respectively of the raceway. The guide members cl, 6 of each bobbin carrier are connected to each other by a barrel 7 which has a collar 9 adapted for engagement with grooves in wheels, as h, so as to prevent the bobbin carriers from being flung outwardly by centrifugal force, and said guide members (if, e, of each bobbin carrier are rigid with the carrier and convexed in oppositedirecions with their convex'surfaces facingeach other, as more particularly indicated in the several views, showing successive positions of the respective guide members, presented in Figs. 3 and 4e, wherein the bobbin carriers 0 are denoted by the small dotted circles at the center of said guidemembers. The barrel 7 is of considerable thickness. The wheels 71 journalled on shafts 2', are integral with sleeves which carry camsk, Z and bobbin drivers m, n. The "rotating drivers m, n carry the'bobbin'carriers around with them in the manner well known to all who are versed in the construction'of braiding or plaiting machines. The functions performedby the cams 70, Z are illustrated more clearly in Figs. 3 and at. In each of these figures five raceway sections and corresponding positions of the gcams and bobbin carriers in the same are shown. Fig.

8 shows a section through the inner and upper part of the circular raceway on the line C-D and illustratesalternating positions of the bobbin carriers. In Fig. 3, the parts I, II, III, indicate the raceway part I) for the guide members 6 and also said guide members, by solid lines, and denote the raceway part a and the guide members (Z cooperating therewith by dotted lines. Fig. 3 thus represents a portion of the circular raceway composed of the parts Z) and 0;, and the parts I, II, III, may be said to be repetitions with the exception that they illustrate successive alternating positions, on one quarter turnsof the wheels h, ofthe respective guide members .6, d and cams Z during the travel of the bobbin carriesalong the said. raceway. I Fig. 4 shows a similar section on the line E-F of the outer and lower part of the circular raceway and illustrates alternating positions of the bobbin carriers which correspond to the bobbin positions shown in Fig. 3. Inthese figures the bobbin drivers which carry the bobbin carriers around with them in the well known manner are .not shown. The cams 7c and Z, and the guide cmembers d and 0 attached to the bobbin carriers are,

however, shown in section. In Fig. 4, the parts I, II, III indicate the raceway part a and-the guide members (i therefor by solid lines and the raceway part band guide-members e therefor by dotted lines, and the parts I, II FIII of, Fig. 4 may be said to be repetitions except that they show successive alternating positions of the respective guide members cl, e and cams 70 on one-quarter turns of the wheels h duringthe travel or the bobbin carriers along the circular raceway composed of said parts a, 1). Figs. 3 and 4 taken together illustrate by solid lines the movements of the guide members 6, d respectively and their respective cooperating cams Z, 70 along the ra-ceway'parts b, a, and as further indicating the relation of the guide members to the guide members 6, and vice versa, Fig. 3 shows the guide members 61 by dotted lines, while Fig. 4 indicates the. guide members i e by dotted or broken lines.

In Fig. 3 the lower part'a of the raceway is indicated in broken lines and represented as if its arcs were of the same size as those of the upper part 6. Since the parts shown in broken lines and those shown in solid lines/in Figs. 3 and 4 are in different planes or concentric circles they will never be in each others way and can therefore never collide when traveling along the racew y. Thus in the case of division 1 of Fig. 3 for example, it should be remembered that the cams Z, the guide member 6, and the raceway section b all lie in one and the same plane or circle, and this also applies to the guide members 6 and cams Z of the other divisions 2, 3, 4 and 5 of Fig. 3. The arrows associated with thevarious divisions of Fig. 3 indicate the direction of rotation of the bobbin drivers. Let 'us consider the bobbin carrier located between the division's 1 and 2 of 'Fig. 3 for example which is driven upwards in Fig. 3 by its driver. It is seen that the upper end or". the guide member 6 is engaged by the upper part b of the raceway. The cam or steadying member Z bears against the guide member 6 and keeps it steady during its further travel along the raceway section of division 2, the steadying eflect being caused through the two parts 6 and Z" rolling against each other. As further explaining the movements of the bobbin carriers, I have lettered the bobbin carrier in the crossing between divisions 1,

'2 of part I, F ig. 3, as c and'the'carrier at'the bottom of saiddivision 2 as 0, and

on the next one-quarter 'turn'of the wheels;

A; in the direction of the arrows in said dlvlsio'ns 1, 2, the positions of the parts ShOWII' ID divlsions 1 2 of part II will have i been reached, the bobbin carrier 0' having moved to the top: of division 2 and fully engagmg'the raceway Z) through its guide member ejand the bob-bin carrierc having reached the crossing between divisions l and 2 on its way to division 1. The guide member (Z of this carrier 0 previously engaging the part a of the racewayis now graduallydis'engaging from said part a and the guide member 0 of the same bobbin carrier 0" is cooperating in the crossing" with the raceway part '2) 111 division 1, part II, the cam Z in division 2, part II, steadying the said guide-member a during its further and 3 in Fig. 3 passes over to the sectionor division 3 because the lower end of its guide member (Z, Fig. 4, is engaged by the part of the raceway a situated in the same plane or circle with this member d, while the associated guide member 6 passes by the V raceway awithout touching it. A steadying member or cam 70 not shown in Fig. 3, but in evidence in Fig. 4, steadies'the part (lot the bobbin carrier during its further travel onto the raceway'section of division 3. It is thus seen that the bobbin carriers are well guided and steadied at the places where they pass from one raceway section to another, orfrom one part a to another 5 of the raceway or vice versa.

The parts a and tor the raceway as shown may be said to be situated in diflerent planes, concentric circles or tiers and their location is' described by corresponding terms inthe following claims.

In Figs. 1 and 2, I number the bobbins l0 and direct attention to the fact that they are beyond or eX-terrior to the guide plates and that the thread from eachbobbim'following the arrow lines shown, passes through a. hole in the arm ll'and thence enters the adjacent or lower back end of the bob-bin carrier 0 and passes through a channel eX- tending longitudinally through said carrier and issues at the forward end of the carrier. The series of radial dotted lines at theright hand portion of Fig. 2 indicate thejpaths of the braiding threads converging at the center of the machine.

There are gaps or spaces in the crossings between"the concave arcs of the raceway parts a, b, and the guide members d,fe, should bea little longer than these gaps or spaces. In F ig. 4, part I I denote'the up, au

by the dotted line Z, so as to indicate the difference in length between the gaps and guide members.

The drawings illustrate my invention embodied in a horizontal braiding machine but is equally applicable for vertical braiding machines.
